Mr. Mars Man is an alien, and he will look different for each one of you. In this lab activity, you will be flipping coins to see what genes your Mr. Mars Man will have. Mr. Mars Man can be hand-drawn by you and submitted through a photo or scan, or can be created through a computer drawing program like the one in Microsoft Word. Your alien will have 10 traits. Each of these traits is determined by tossing two coins at the same time. You will get two heads, two tails, or one of each, and follow the directions to figure out each trait. We are considering heads to represent the dominant trait and tails to represent the recessive trait. Think about each coin as a parent of your alien. Once you have a list of your unique alien's 10 traits, create your portrait. Make sure you hand in a list of the 10 traits with the portrait, and whether each trait is dominant or recessive. The first flip is detailed for you, and you should be able to do the rest on your own. It will be easier to draw your alien if you figure out all 10 traits before you start drawing. Dominant = Round body (R) Recessive = Long body (r) Two heads would be RR, meaning your alien has a round body. One head and one tail is Rr, meaning your alien still has a round body (because round is dominant!) Two tails would be rr, meaning your alien will have a long body. Your written section would say, for example if you got an Rr, “Rr = Round body, dominant.” Curly hair (C) Straight hair (c) Big nose (B) Small nose (b) Five eyes (F) One eye (f) Pointed teeth (P) Round teeth (p) Giant mole (M) No mole (m) Spiky tail (S) Paddle tail (s) One ear larger than the other (E) Both ears tiny (e) Likes to wear lovely dresses (D) Likes to wear pants and boots (d) Has heavy eyebrows (H) Has thin eyebrows (h)
